MicroAmp MH-2 Housing

For Dual MB Circuit Boards

The MicroAmp MH-2 housing will accommodate two MB series circuit board to create a completely shielded 2-port circuits. Boards are

available for microwave amplifiers, filters, log detectors, frequency multipliers, dividers, and operational amplifiers that can be cascaded

together in a single housing to create more complex circuits. After assembling the desired MB circuit boards, simply drop them board into

the housing cavity and screw the boards in place using #1-72 socket head cap screws with a 0.050" hex key. Join the two circuits together

using a small bridge wire, foil ribbon, zero-ohm resistor, or capacitor. Then insert the SMA connectors into the side walls and secure them

with #2-56 mounting screws and solder the center pins to the circuit board pads. The ground turret terminal and 1000 pf bias feed-through

are then installed into the housing side wall and the bias connection is soldered in place from the circuit boards to the feed-through pin using

a small gauge wire. Install the feed-through carefully with just enough torque (2 in-lbs max) to secure it in place. A cover attaches to the top

of the housing with #2-56 screws to complete the shielded assembly. The finished housing can be mounted to a baseplate using the corner

through holes.
